Some basic phone security practices: 1. Set a sufficiently strong alphanumeric password for your lock screen. 2. Remember to reboot your phone weekly to reset

Some basic phone security practices: 1. Set a sufficiently strong alphanumeric password for your lock screen. 2. Remember to reboot your phone weekly to reset any non-root malware. 3. Disable multimedia in the SMS messaging app as it's a vector for Pegasus style malware. 4. If using Signal, go to Settings, Privacy, Phone number, and set everything to Nobody. This again blocks messages from unknown users that could be a vector for Pegasus style malware. I wish there was a system-wide permission to audit and/or disable screenshots, but there isn't.
